"In the three days of the Battle of Gettysburg in 1863, more than 7,000 people died in the bloodiest battle fought to date on U.S. soil. It's easy to imagine that some of those people still walk the battlefield today! This book gives readers the chance to look back in time at the history of Gettysburg, from the first shots fired to the desperate, bloody fight to the Confederacy's final retreat. Primary sources highlight the battle's historical context as a major turning point in the American Civil War, while maps show details of the site where so many soldiers died-and where their ghosts are still said to linger today"-- Provided by publisher.
